Abstract

Gedeon DC flows impose a serious influence on the performance of thermoacoustic systems with topological loops. This article gives a quantitative analysis of DC flow influenced in a normal double inlet pulse tube cooler and a feedback pulse tube cooler with a numerical model based on linear thermoacoustic theory. Different configuration characteristics and cold end temperatures are evaluated. The results help to establish a reasonable evaluation of DC flow influence on the system performance.
